Sensors Monitor Temperature at Multiple Locations

Microchip Technology’s EMC181x 1.8V temperature sensors include the industry’s smallest five-channel temperature sensor with standard lead spacing. The EMC181x temperature sensor family also introduces system temperature rate-of-change reporting, a feature that provides advanced warning on how the temperature of a system is fluctuating.

 

Monitoring temperature at multiple locations with a single, integrated temperature sensor, the EMC181x temperature sensor family offers a variety of remote channels at 1.8V operation to fit different design needs, ranging from two to five channels. The family is viable for applications migrating from 3.3V systems to lower voltage rails, such as battery operated IoT applications, personal computing devices, Field-Programmable Gate Arrays (FPGAs) and Graphics Processing Units (GPUs). Additionally, the EMC181x family is register and voltage compatible with Microchip’s 3.3V EMC14xx temperature sensors, making migration to 1.8V testable and achievable. With the three-channel sensor available in an 8-pin 2 x 2 mm footprint and the five-channel in a 10-pin 2 x 2.5 mm footprint, the sensors can also reduce the number of devices needed for remote temperature monitoring.

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.

 

The ADM00773 evaluation board provides everything needed to demonstrate the 1.8V three-channel two-wire EMC1833 temperature sensor and gives functional insight into the other EMC181x family members. It facilitates evaluation of programmable features such as rate of change, temperature alert limits and Resistance Error Correction (REC), in addition to providing off-board temperature measurements and data logging. The evaluation board connects to a PC through a USB interface board and comes with the Microchip Thermal Management Software Graphical User Interface (GUI). 

 

Pricing and Availability

 

The EMC181x family consists of five devices, all available today for sampling and volume production. Pricing begins at $0.44 each/10,000 for the EMC1812T two-channel sensor. For more details, checkout the EMC181x datasheet.
